Pre-Solids Separation System OVERVIEW Halliburton Testing and Subsea offers enhanced pre-solids separation and removal with unparalleled removal efficiencies as high as 99% of solid particles > 10 μm. The system is comprised of two 100% pre-solids separation vessels, each housing an interchangeable cyclonic insert to handle varying flow conditions. The sand accumulator is integral to the vessel and designed to be dumped while one of the vessels is offline and the other vessel remains online. The system is designed to be placed directly upstream of the Halliburton three-phase test separator to remove any solids, improving the efficiency of the three- phase separator. In operation, the entire well stream flow is fed into the pre-solids separation skid to one of the vessels operating under normal conditions, while the other unit is in stand-by or being purged of solids. Cyclonic separation of the solids takes place in the insert, with sand falling down into the integral accumulator vessel. The selection of the insert size will suit the particular design conditions specified, covering a range of flow rates, fluid properties, and sand loading. Emptying (purging) of one of the vessels involves isolating the vessel from the process by using the valve arrangement, venting the vessel to reduce pressure, and then flushing out the recovered solids by using a clean water source. To minimize the ingress of oil and keep the solids discharge process as clean as possible, the vessel that is being purged will be filled with flushing water before it is re-opened to the process.

Pre-Solids Separation System
OVERVIEW
Halliburton Testing and Subsea offers enhanced pre-solids separation and removal with unparalleled removal efficiencies as high as 99% of solid particles > 10 μm.
The system is comprised of two 100% pre-solids separation vessels, each housing an interchangeable cyclonic insert to handle varying flow conditions. The sand accumulator is integral to the vessel and designed to be dumped while one of the vessels is offline and the other vessel remains online. The system is designed to be placed directly upstream of the Halliburton three-phase test separator to remove any solids, improving the efficiency of the three-phase separator.
In operation, the entire well stream flow is fed into the pre-solids separation skid to one of the vessels operating under normal conditions, while the other unit is in stand-by or being purged of solids. Cyclonic separation of the solids takes place in the insert, with sand falling down into the integral accumulator vessel. The selection of the insert size will suit the particular design conditions specified, covering a range of flow rates, fluid properties, and sand loading.
Emptying (purging) of one of the vessels involves isolating the vessel from the process by using the valve arrangement, venting the vessel to reduce pressure, and then flushing out the recovered solids by using a clean water source. To minimize the ingress of oil and keep the solids discharge process as clean as possible, the vessel that is being purged will be filled with flushing water before
it is re-opened to the process. Each of the vessels on the skid is equipped with site glasses so that operators can visually inspect solids accumulation. Normal practice is to periodically dump the solids based on field conditions (for example, more frequent dumping required when solids loading is expected to be higher during initial phase of well clean-up).
